pod config: add a CreateCommand field

Browse Source 
Add a `CreateCommand` field to the pod config which includes the entire
`os.Args` at pod-creation.  Similar to the already existing field in a
container config, we need this information to properly generate generic
systemd unit files for pods.  It's a prerequisite to support the `--new`
flag for pods.

Also add the `CreateCommand` to the pod-inspect data, which can come in
handy for debugging, general inspection and certainly for the tests that
are added along with the other changes.
